GAS-BURNER.

" Be it known that I, WILLIAM I a c1tizen of the United States, residingat v Chicago, in the county of Cook and State of Illinois, have inventedcertain new and useful Improvements in Gas-Burners, of which thefollowing is a specification. 1-

' The'subject of the present invention is a gas burner for producingheat for any and all purposes and the invention relates moreparticularly to burners used for cooking 5 the improved burners ofpreferred construc purposes and for the heating of water in the boilersof circnlatingsystems usedfor do mestic purposes. Preferably, gasburners used for these purposes are circular in outline, but the presentinvention has nothing to do with the general shape of the burner, whichis, in all cases, determined by the shape of the article or vessel to beheated or by the shape of the space available as a combustion chamber.For the urposes of this specification, however, the timer may beconsidered as of general, circularv outline,

the original aim of the invention being to provide an improved burnerparticularly' adapted for water-heaters of the classshown and describedin my application filed January 28, 1911, Serial No. 605,225, and forgas ranges. I-

The objects of the invention, generally stated, are to provide animproved gas burner especially adapted for the uses named-improved withrespect to its efficiencyand to its details in mechanical construction.

.Tothe'se ends the invention consistsinthe features of novelty that arehereinafter described with reference to the accompanying drawings, whichare made a part of this specification and in which:

Figure 1 is a perspective view of one of tion, a fragmentary portionbeing broken away forthe purpose of showing the interior construction. Fg. 2 is a horizontal-section thereof taken ina plane between the top andbottom of theshell of the burner and showinga modification in the formof the jet ig; 2,"l0oking p arrows.

cylindrical wall, 1, and top and bottom walls, 2 and 3, respectively,the interior space of the shell being divided into two separate andwholly independent chambers, 1 and 5, by an annular partition, 6, which01I1S the top and bottom of the shell gas- .tight. For some purposes,as, for example, for use in connection with a water-heater of the classshown and described in my application aforesaid, .the burner is providedwith a central, vertical opening, 7, for the reception of a pipe or thelike, and, in this event, the annular wall, 8, of this opening alsoforms the inner wall of the chamber, -5.

lating and controlling the supply of gas to one of the mixing'chambersbut it will be understood that the valve devices for both mixingchambers are precisely alike. The delivery branches, 11 and 12, of themixing chambers are connected by an integral web, 19, so that they maybe handled as a single part and held permanently in fixed relation toeach other, and theluplper ends of these branches are provided witflanges, 20 and 21,'which are bolted to the bottom 3, of the shell. Themixing chamber, 12, has a single right angular bend dividing it into avertical and a horizontal branch joining each other in the shape of anL-, while the mixing chamber, 11, has three right angular bends, 22, 23and 24, dividing it into four branches which join each other in the shae of two- Ls so arranged that the two branc es of one of said Ls liewith their axes in a lane perpendicular tothe plane in which t e axes ofthe two branches of the L first aforesaid lie, while the second of saidtwo Ls lies with the axes of its two branches in a plane which isparallelwith the plane last aforesaid. In

' other words, the vertical branches of the two.

US of the mixing chambers, 11 and 12, lie

with their axes in the same plane, while their respective horizontalbranches, 25 and 26,

cross each other at right angles, the horizontal branch, 26, lying inthe plane of the axes ofthe aforesaid two vertical branches, whilethe-horizontal branch, 25, lies in a plane perpen'dicularto the commonplane of the'axes of said vertical branches. This arrange- ;ment allowsthe vertical branches of the two mixing chambers to be located onebehind the, other and also allows the horizontal branch, 26, of thechamber, 12,. and the hori-' zontal branch resulting from the bend, 24L,

- "of the chamber, 11, to lie inthe same horizont-al plane and terminatein proximity to a gas supply pipe which is common to both of them. Forconvenience inconstruction, the

I mixing chamber, '11, may be formed in two parts and theirmeeting facesprovided with flanges,i"27, adapted to be secured together by. bolts.

The top of the'shell is provided. wit-ha plurality of tubularprojections, 30, located- -are cast integrally, so that the lower endsof the tubes join the bottom of theshell gastight,-while their upperends, when the castmg comes from the mold, joins the top ofthe shellgas-tight. In this connection, it should be explained that alldownwardly presented surfaces which are exposed to the interiors of thechambers, 4 and 5. are to be considered as parts of the top of theshell. In this preferred form of. the invention each of the tubularprojections is provided with a 'nute annular orifice ,or. jet opening,35, thereby forming a burner tip. Each. of the jet openings ispreferably made by the use of an annular'cutter, the internal diameterof which is'equal to the external-diameter of one of the tubes (32 or33) so that a portion of the tubular projection which extends upwardfrom the top of the shell as it comes from the mold forms an upwardcontinuation of the tube, the cutting being continued farv enough tocause the annular orifice to communicate with the chamber, 4 or 5, as

the case may be. The tubes, 32 and 33, form ducts through which asuificient'quantity of air to properly support combustion passes upwardand is discharged within the hollow jets of aswhich escape from theannular jet openings, after the mannerof an Argand .cut, a plurality 0burner. Or, in place of a single-annular minute openings or drill holes,35?, may be made in each of the tubular projections andarranged-in acircular series around the upper end of each 0f the air tubes or ducts.

It will be understood that the invention is not limited to anyparticular number of burner tips or tubular projections having jetopenings, nor is it limited to a burner having any particular number ofchambers, each common'to a number of such burner tips. It will beunderstood also that the object .in providing a plurality of suchchambers is to enable a greater or less number of burner tips to beused, accordingly as more or less heat is desired. 1 lVhat I claim asnew is: a

1. A gas burner having a hollow shell, a

partition within the shell dividing its interior into a plurality ofseparate and independent chambers, said shell. having openings,communicating with said chambers,

respectively, for the admission of gas thereinto, separate andindependent mixing tively, a separate valve mechanism forcontrolling thesupply of gas to said mixing chambers, 'each-..o f said mixing chambershaving-two branches united in the formof an L, the discharge branchesbeing vertical and located one behind the other in a plane whichiscommon to their. axes, while one of the horizontal branches is locatedwith its axis in the same plane and the other of said horizontalbranches is located with its axis in a plane aforesaid. 2, A gas burnerhaving a hollow shell, a partition located within the shell and div dingits interior into a plurality of chambers, said shell having openingscommunicating with said chambers, respectively, for the admission of gasthereinto, a plurality of burner tips communicating with said chambers,respectively, separate mixing chambers, the discharge branches of whichcommunicate with said openings, respectively, and lie in a verticalplane which is common to their axes, while their intake branches lie ina horizontal plane which. is common to their perpendicular to the planefirst chambers, the discharge branches of which communicate with saidopenings, respecaxes, one of said chambers having an intermediateoff-set portion which lies with its axis in a horizontal'plane above thehorizontal plane aforesaid and in a vertlcal plane which isperpendicular to the vertical plane aforesaid.
